- Groshong line
A Groshong line is a type of tunneled intravenous
catheter used for central venous access. Groshongs may be left in place for extended periods and are used when long-term intravenous therapy is needed, such as forchemotherapy . Similar to theHickman line , the tip of the catheter is in thesuperior vena cava , and the catheter is tunneled under the skin to an incision on the chest wall, where the distal end of the catheter exits the body. In contrast to theHickman line , the tip of the Groshong line has a three-way valve which allows infusion as well as blood aspiration while reducing the risk of clotting, air embolism and blood reflux.The insertion of a central Groshong line is usually done under
local anesthetic by a radiologist or surgeon. It involves two incisions, one at thejugular vein and one on the chest wall. At the former, a catheter is inserted into the vein and advanced into thesuperior vena cava . It is then tunneled under the skin to the second incision. The first one is then sutured. Throughout the procedure, ultrasound andX-ray s are used to ascertain the positioning of the catheter. Groshong catheters come in PICC line variations as well.The Groshong catheter is a trademark of Bard Access Systems.
